High quality upscaling
Is it possible to do high quality upscaling (better than with a tv) with handbrake? I would like to upscale to 1920x1080 from PAL-VHS and better.

Re: High quality upscaling
Why?
Seriously, most current TVs now have built-in scalers that are exceptional quality. So scaling your videos at encode time only inflates file size for no perceptible gain in quality.

You are right, but in certain cases it could be better to upscale slowly, than on-the fly. I think on something like -sws 9 (Lanzcos) with mencoder.

Re: High quality upscaling
I'll be nice an assume you know what you are doing 
HandBrake's scaler is libswscale and we use the Lanzcos option.

At least I would like to test the difference. Most people are ripping dvds or blurays, I noticed there is a big difference in optimizing the quality when the source is an own camcorder video, especially very old ones.
